Chapter 6 Troubleshooting and FAQs

Everything appears to be setup properly with the Modem, but I can’t con- nect to the Internet. What should I do?

If the Modem is not dialing out, it may need to be power cycled. To do this, unplug the power cord from the Modem. Leave it unplugged for about 30 sec- onds, then plug it back in. The Modem should now be able to dial out.

How many computers can be connected through the Actiontec Dual PC Modem?

The Modem is capable of 252 connections, but we recommended to have no more than 5 connections. As the number of connections increases, the available speed for each computer decreases. Keep in mind that a dial-up connection has a very limited amount of bandwidth.

Is my Modem a firewall?

Yes. The Modem provides its security through the use of a NAT firewall, which acts as a physical barrier between your network and the Internet.

What is NAT and how does it protect my network?

NAT (Network Address Translation) is a level of security which masks the pri- vate IP addresses of the computers on your network with a single public IP address. With NAT, the private IP address of any computer on your network is never transmitted over the Internet.

Which Virtual Private Networking (VPN) protocols are supported?

The Modem does not support VPN.

Can I use Internet firewall or security programs with my network?

Because the Modem uses NAT firewall security, it is not necessary to use any other program (BlackIce Defender, Norton Internet Security, or ZoneAlarm, for example) for security. The use of third party firewall or Internet security soft- ware is not recommended, as certain programs will create problems on a private network.
